Thanks to the great and distinguished @AgentX1976 for designing this photo. This is a PERFECT example in my humble opinion of a supporting photo.
Now, I realize all of your specific situations may not have a street sign in it, but you get the idea. Use the current terrain and landscape to paint the picture for the reviewer.
If you are reading this, I’m rooting for you!
It’s a thing of beauty
Here’s one from a LFL at a local park that isn’t on satellite or Street View. Street View doesn’t go through the park either, just on the nearest street, and the street entrance to the park can be seen, along with some other Wayspots (basketball court and picnic shelter), as well as that it’s by the crosswalk to the campground. I also made note it’s by the playground, which is just north of the basketball court.
Also, let’s keep the good examples coming!
This is one I did recently, I leveraged the permanent food truck in the background and the distinctive bridge to help ground the location of the painted box.
Ignore the supporting text… Emily picked this up before I could edit it 
I’ve highlighted items on the supporting photo before but using just the doodle tool so the results aren’t pretty. Still, it does seem to help a bit.
This isn’t the best example, but I think this ticks the boxes. This proposal was for a WWII memorial plaque and got approved back in May. The plaque is on the wall near a restaurant, the awning of the restaurant is visible on Street View. It’s down the block from an existing Wayspot (which is a mural at the other restaurant in the background), with a nice wide sidewalk where folks could gather and stand without blocking access to the restaurant or impeding other pedestrians.
Hi
I have a question to this topic.
Don’t you think that supporting photos like this couldn’t be misused for abuse? Influencing reviewers?
Maybe the style of arrows…
On top: you can’t find anywhere, that the supporting photo is excluded to the “photo rules”.
I can’t speak for anyone else, but I added the arrows and text just now in paint. When I submit I don’t use arrows or edits to the photos.
That is actually a great point and I can’t find where it specifically says that supporting photos do not have to follow the rules, but
Help > Photo Guidelines
https://wayfarer.nianticlabs.com/new/help/photo-guidelines
For supporting photographs, submit a photo that includes the object. The photo should allow the reviewers to confirm the location of the object by the surrounding recognizable features that can be spotted on satellite view or similar.
does encourage you to submit a supporting photo that will help reviewers. Then the next section begins
A high-quality photo of a Wayspot is:
so I have always taken what comes next to be specifically for the Wayspot photo.
I still don’t use Street View or third party photos there, but only because I don’t want to raise any red flags for my main photo.
I rarely augment my supporting photos, but sometimes just words won’t do and arrows are necessary. Like this one where I needed to show the pathway junction that does show on satellite view as well as the marker:
And this one that shows the locations of other Wayspots to show that this isn’t a duplicate:
Hey there @NianticAaron - What are your thoughts on this? We don’t want to break any rules. But I think this is very helpful using ONLY ON SUPPORTING photos. Can you weigh in on this? Please? Thanks.
Tbh I wouldnt see this as influencing reviewers. Someone adding some lines or arrows to help me identify something in a supporting photo isnt telling me how to vote on the submission. So as long as they dont write “please approve” on the image I would prefer something that helps me identify vs having to squint and use streetview to even tell if its there since some literally just turn around and take a picture of whats behind them without the wayspot in it
Interesting topic! I don’t see any issues with using such supporting images. These can indeed help reviewers.
This is definitely a possibility. These can be used to identify the submitter but so can the supporting text. I understand your concerns but the abuse needs to be catered to on a case to case basis (if there is evidence to suggest that).
I hope I did not complicate the issue at hand 
thanks for weighing in!
I have done this before, made a collage with a zoomed in part of a picture. The dodgy arrow was included during review
You are going to make @Glawhantojar dance on a cloud. His entire mission in life is to get Explorers to get better with their supporting photos. We are def going to start making this part of our submission process. Will report back!
I generally do not edit my photos in any way, I prefer doing the initial photos on-site and then just editing text later - but here’s one of my supporting photo/information combos for a footbridge along a walking/biking trail that I hope allowed users to better analyze location -
I do know what you mean here though. There for a while I was seeing supporting photos like this with a big circle pointing out something obvious - this was for the volleyball court and I did wonder if this was an identifier.
Time to get a telescope? Just kidding
That’s very noble of him. Let him know that I wish him well and am willing to do whatever I can to help along the way.
I would love to hear back about the experience.
Just a quick addition, adding a link to unlisted or public gaussian splats in the supporting statement can go a great length too.
Happy exploring 
Hi, i’ve been reminding people not to do that because the splats are tied to your Niantic ID and can be “submitter identifiable” or even “influencing reviewers” if the submitter becomes known. Has that issue been resolved?
